Procedure

A solution that consists of 210 mg (0.86 mmol) of 5-aminoquinoline-2-carboxylic acid diethylamide, 266 mg (0.86 mmol) of 4-(5-fluoro-2-methoxyphenyl)-2-hydroxy-4-methyl-2-(trifluoromethyl)pentanal and 0.36 ml (1.73 mmol) of titanium tetraethylate in 15 ml of tetrahydrofuran is stirred for one hour at room temperature and then for 3 hours at 80° C. After removal of the solvent and purification on silica gel with hexane-ethyl acetate (0–70%), 230 mg (52% of theory) of the product is obtained.
